A V4 step's input side is what SETTLE or SETTLE_ALL names, else the one currency its swap actions spend and never buy; its output side is what TAKE or TAKE_ALL names, else the one they buy and never spend. Amount sums the amountIn of the actions spending the input side, shown only when each states one; Min. received likewise. An unread swap action leaves the sides to SETTLE, SETTLE_ALL, TAKE and TAKE_ALL, with no figure. A step with a swap action always sets the output side, sets the input side only if no earlier step did, and leaves a side its rules cannot name unknown, with no figure. SWAP_EXACT_OUT spends its first path entry. Model: opus-5-5
